The biofuel industry has had ups and downs, so the latest news should warm some hearts. The results of a new study show that biofuels used in jet engines a good shave off particulate emissions. For those of you looking for some good news about biofuels and carbon emissions should see some other studies, but the results still show a very promising path to reduce the effects of air travel on climate. Researchers at the national research Centre of Egypt has produced biofuels suitable for aircraft after the semi-industrial experiment successfully conducted last December.
The Centre was officially commissioned by the Civil Aviation Department of Egypt to find the local biofuel to power the aircraft. This is to support the implementation of the plan of the International Air Transport Association, which aims to reduce carbon dioxide emissions caused by Aviation Company by 2050. Commercial aviation contributes about 2 percent of global carbon emissions per year.
Gizine El Diwani, Professor of chemical engineering at the Center and a semi-industrial experiment Department, says that it all began with the production of biofuels for cars. Researchers make biodiesel from Jatropha seed oil content is between 20-25 percent. The oil can be easily extracted using organic solvents such as hexane, according to El Diwani, “Globally, the cheapest price of biofuels is 90 percent higher than the average of fuel; this is due to the high cost of the raw materials needed for the manufacture of biofuels.”
Because of the nature of castor oil are different from traditional in terms of engine oil viscosity, density and level of combustion that has to go through a number of chemical processes that are simple enough to be adapted for use in machines running. At this stage of it, the fuels are suitable for car. To suitable for jet engines, must be able to withstand freezing to minus 45 Celsius degrees at least. The research team is trying to accomplish this at a later stage in the development of fuel.
El Diwani “explains:” we managed to raise the freezing point of the distance the fence of biofuels through the process of thermal cracking, using thermal stimulation at high temperature and pressure to bring oil [temperature down] to minus 40 degrees [Celsius] without [it] frozen. Then, we were able to reach minus 45 degrees with introduce some [chemistry] additive. “El Diwani “added that Egypt has successfully cultivated an extensive land area with a distance of the fence, in the desert of Upper Egypt is estimated to be around 1000 hectares. The success of the experiment the production of biofuels is expected to encourage the research team to improve widely provided to grow trees.
Khaled Fouad, a researcher in the field of aviation engineering at Zagazig University in Egypt, saw a fundamental advantage in the production of biofuel from castor bean oil. “This is a tree of non-edible for humans and animals, which grows in sandy desert soil and gets irrigated with sewage water makes it a unique source of biofuels.” However, a serious challenge in designating Fouad production costs is high, which he attributes to the use of additives to lower the freezing point. “Globally, the cheapest price of biofuels is 90 percent higher than the average of fuel; this is due to the high cost of the raw materials needed for the manufacture of biofuels, “he said.
The researchers are currently working to resolve this, according to Salwa Hawash, a member of the research team. “We will try to eliminate materials [current] used to lower the freezing point by adding hydrogen to a thermal cracking process, and we hope positive results will be cutting costs.” Other semi-industrial experiment on biofuels will be made after introducing this type of crack. The team hopes to finish all industrial experiments and start using locally produced biofuels in planes at the end of 2017, according to El Diwani.”
